ath5k: Update gain_F calibration code and add documentation

Browse Source 
* Update and cleanup rf gain optimization code

 * Add comments and refferences to docs and use sane function names

 * Use only step index on ath5k_gain, no need to have a pointer to
   the current step since we can determine te step from it's index,
   this also allows us to put all other structs on rfgain.h and cleanup
   ath5k.h a little

 * No need for ah_rfgain variable, we use ah_gain.g_state for everything

 * Tested on RF2112B chip but gain_F calibration is not yet done
   (we will finish this on the next patch where we'll rewrite rf-buffer
   handling)

 * Use initial rf gain settings for 2316 and 2317 SoCs introduced on a previous patch

 It seems big but it's mostly cleanup, very few functional changes have been made on phy.c
